I really liked this idea when I first saw it but Graeme's response about the minimum turning circle of the cars got me thinking it may not work in RC (even assisted) as well as it does with slot cars.

With slot cars you could really get some controlled drift around these with a bit of practice but I'm not sure if the AI could keep up with it, it may end up just a really slow turn at full lock, any quicker and you'd spin off?
